HAT-BRIM-CURLING- MACHINE.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed. January 17, 1914. Serial No. 812,844.

To all whom it may concern:

Be it known that I, GUsTAv SncsoHNmDnR, a citizen of the United States,residing in Yonkers, VVestchester county, New York, have inventedcertain new and useful Improvements in Hat-Brim-Curling Machines, ofwhich the following is a specification.

This invention relates to hat-brim curling machines employing acurling-shoe and a curling-hammer cooperating therewith to curl the brimbetween the hammer and the shoe, such for example as the machine shownin my prior Patent No. 7 79,242 of January 3d, 1905.

The objects of the present invention are to provide automatic means fordampening the brim; also to improve the action of the hammer; and torender the feeding-devices more reliable in operation and moreconvenient of adjustment than hitherto. The first of these objects isaccomplished by arranging a dampening-belt adjacent the path of the brimso that the belt contacts with and properly wets the brim before itsentrance between the shoe and hammer. The action of the hammer isimproved by mounting the same on a spring-metal arm having properflexibility to permit the required movement of the hammer hithertoobtained by pivoting the latter, whereby the play inseparable from wornpivoted parts is eliminated. The actuating mechanism for the feed-rolleris rendered certain in its operation, and convenient of adjustment, andan improved means of adjusting the feedingfinger is provided.

In the accompanying drawings, Figure 1 is a top-view of a machineembodying the invention, Fig. 2 is a vertical section on line 22 of Fig.1, Fig. 3 is a vertical section on line 3-3 of Fig. 2, Fig. t is ahorizontal section on line 4- 1 of Fig. 2, on a larger scale, Fig. 5 isa vertical section on line 5-5 of Fig. 3, on a larger scale, and Fig. 6is a vertical section on line 6-6 of Fig. 4, also on a larger scale.

Similar reference numerals indicate corresponding parts in all thefigures.

On the bed 10 of the machine is located the curling-shoe 11, andadjacent the same at the entering side of the shoe are thefeeding-finger 12 and the brim-guide 13, and removed therefrom thecrown-guide or button 28, and below the shoe the heatingburner 29, allthese parts being well known in hat-brim curling machines.

Below the bed is supported a depending bracket 14, carrying a horizontalroller 15. Also below the bed 10 and inclosing said bracket and roller,is a receptacle 16 for the water or other liquid used for wetting thebrims of the hats prior to curling. For supporting the receptacle 16,two angular spring-clips 17 are attached to the bed 10, and engage lugs18 on the receptacle, as shown in Fig. 2. By pressing the clips inwardby hand they are released from the lugs, thereby permitting the easyremoval and replacement of the receptacle. A dampening-belt 19, made ofloose cotton fabric or wicking, or any other material suitable fortransferring liquid from the receptacle to the hat-brim, passes aroundsaid roller 15 in the liquid 20 in the receptacle, and upward through anopening 21 in the bed 10 and thence continues upward and over adriving-roller 22. The main-face 25 of the brim-guide extends at itsforward portion 59 to the hook 26 of the same, and said forward portion59 is spaced from the body 27 of the brim-guide, forming an opening 23in which the wet-belt passes upward. The forward extension 59 of thebrim-guide protects the lower portion of the hat-brim from contact withthe wet-belt, but its upper edge is lower than the upper edge of themain part of the guide, and suiiiciently low to expose the upper part ofthe brim to contact with the wet-belt over the full width of thewet-belt and for a vertical distance of approximately one-ouarter of aninch. this being a proper distance for the required wetting. The belt islocated close to the body-portion 27 of the brim-guide and by the sameis kept in close contact with the brim, during the passage of the brimin the guide. After passing over the roll 22 the belt passes down at theback of the brimguide to the receptacle. By means of the wet-belt, thebrim of the hat is automatically properly dampened for the curlingoperation of the hammer, so that the handdampening of the brim which washeretofore necessary and which was usually performed with a spongebefore placing the hat in the machine, is done away with. The brim-guideis adjustable by swinging the same around its securing-bolt 86 by whichit is fixed in place on the bed 10, and vertically by adjusting thethumbscrew 87 against the ear 88 which is kept normally raised by thespring-tension of the rearportion 89 of the guide.

After leaving the brim-guide, the brim passes between the feed-roller 30and the feeding-finger 12, and enters the shoe, wherein it is acted uponby the hammer 50. Said hammer is provided with the usual hooked forwardend or nose entering the curved groove of the shoe and acting to hammerthe hat-brim 9 therein, whereby the brim is'permanently curled. At itsrear portion the hammer is provided with upwardlyprojecting lugs 51,two'at each side, between which is received a spring-arm 52 which isbolted at 53 to the hammer and supports the same. The arm 52 extendsrearwardly'from the hammer and is downturned and bent forward, as shownclearly in Fig. 3, and at its lower portion is bolted at 54: to a slideor carriage 55 which is longitudinally guided in two transverse keepers56 of a carriagebed 57 which is secured to the bed 10 of the machine.Reciprocating motion is given to the hammer by means of a connecting-rod60 made of spring-metal and bolted at its forward end at 61 to thecarriage 55 and pivot ed at its rear end to a wrist-pin or stud 62eccentric on a head 39 at the end of the driving-shaft 64 of themachine. It will be observed that there are no pivots or other loosejoints whatever between the carriage and the nose of the hammer, hencethere is no opportunity for play in any such joints, which was a seriousobjection in former machines, while at the same time the necessaryyielding of the hammer in vertical directi0n required to cause the sameat each blow to adapt itself to the particular conditions of thematerial between the hammer and shoe, is preserved. The strength of thespring 52 is such not only as to hold the hammer supported against theforce of gravity in the position shown in Fig. 3, but so much more thanthis, that a slight lifting of the hammer out of true position meetswith immediate resistance from the spring-arm 52. In this respect themounting of this hammer differs from those counterbalanced or spring.-balanced hammers heretofore employed in which there was no resistance toupward movement of the hammer. Such hammers had unnecessary anddisadvantageous upward play, resulting in imperfect curling, and unduewear on the overhanging upper edge of the shoe, which are overcome bythe new means of mounting the hammer heretofore described. The hammer isvibratorily supported by the spring, and the axis or point about whichthe vertical movement takes place, is-located outside of thehammer'itself, namely, within the spring, or at the point where thespring is fastened. A further source of difiiculty with hammersheretofore in use lay in the means employed for giving themreciprocating movement, namely a connecting-rod having two pivot joints,one at the carriage and the other at the wrist-pin on the driving-shaft.By employing a spring-metal connecting-rod as described, which isflexible in the direction of rotation of the wrist-pin, theconnecting-rod may be rigidly secured to the carriage. The other end ofthe connecting-rod 60 is turned as an eye 63 around the wrist-pin 62.When, due to wear or any other cause,play occurs at this point, the samemay be taken up readily by contracting the eye by a blow with a hammeror other suitable tool. There is thus no play existing in thelongitudinal movement of the curling-hammer, and the blows of the sameare delivered firmly, uniformly and effectively. In order that theproper adjustment of the position of the hammer may be made, so that thefull benefit of the exact movements of the same are obtained, thespring-arm 52 is provided with longitudinal slots 66 receiving the bolts53 which are threaded in the hammer, so that the hammer may be locatedat any point relatively to the spring-arm necessary to bring the nose ofthe hammer into the exact desired relationship with the shoe. The shoealso is adjustable both longitudinally and laterally, by means oflongitudinal recesses 67 in the rearwardly-projecting ears 68 of theshoe, said recesses being of greater width than the diameter of theattaching-bolts 69 and thereby permitting lateral adjustment of the shoeto the extent of the width of the slots. The carriage-bed 57 is providedwith oppositely-arranged laterally extending lugs or ears 70, 71, eachhaving a recess 72. Said lugs are. preferably cast integral with thecarriage-bed. They rest upon the bed 10, and support the 'carriage bed57 in a recess 49 ofthe same. Bolts 73 of less diameter than the widthof'the recesses 72, clamp the lugs 70 and 71 to the bed. The recesses 72permit longitudinal adjustment of the position of the carriage-bed tothe extent of the difference between the width of the recesses 72 andthe diameter of the bolts 73, and thus afford an adjustment of thekeepers 56 relatively to thecarriage 55.

The feedin'g finger comprisesa strip 12 of spring-metal which is mountedon a rest 41 which is slotted at its rear portion at 42 and secured tothe bed 10 by a-bolt 43 passing through the slot. The rest is thusadjustable longitudinally to the extent of the length of the slot, andangularly about the bolt, so as to place the finger in proper relationto the feed-roller 30. A thumb-screw 47 arranged horizontally in theforward portion of the rest 41 bears laterally against thefeeding-finger at a point some distance back from the feed-roller, sothat the spring-tension of the feeding finger toward the roller may beadjusted and the required pressure of the same obtained for reliablyfeeding the brim. In former machines the feeding finger was secureddirectly to the rest by screws passing therethrough. Such means ofsecuring the finger to the rest did not afford the necessary range ofadjustment of the finger, and did not permit its prompt adjustment orremoval or replacement. These ends are now attained by providing alongitudinal clamping-plate 44, which is secured to the rest by screws45, said plate having at its lower edge an inwardly-projecting flange 46of the same width as the thickness of the finger 12. The finger 12 isclamped by the screws between the clamping-plate 44 and the rest, and isthere held by friction in the desired position, the screws serving as ameans for determining the horizontal position of the same, as shown inFig. 6. For adjusting the finger, or removing the same, it is onlynecessary to release the screws 45 by a backward turn of the same,whereby the clamping-plate is released from the finger and the lattermay be freely moved. The freedom of adjustment of the finger, and itsreadiness of removal, are of great advantage in securing the reliablefeed of the hat brims and quickly changing the machine from feeding onestyle or shape of brim to another.

The feed-roller 30 is mounted at the lower end of a vertical shaft 31supported in a standard 32 which rises from and forms a part of the rest41. At its upper end the shaft carries a bevel-gear 33, with whichmeshes a pinion 34 which is secured to a horizontal shaft 35, the latterbeing supported in side-standards 36, 37, which are bolted to the bed10. From the standard 37 extends laterally a bracket 70, which supportsa shaft 71 on the inner end of which is carried the driving-roller 22 ofthe dampening-belt. A belt-and-pulley transmission 7 2, 73, 74 from thecountershaft 35 imparts motion to the roller-shaft 71. The countershaft35 is driven from the driving-shaft 64 by a belt-and-pulley transmissioncomprising a small pulley 77 on the driving-shaft 64, a larger pulley 78on a sleeve 79 mounted loosely on a stud or short-shaft 99 secured tothe standard 36, a small pulley 80 secured to said sleeve, a largerpulley 81 on the countershaft 35, and belts 82, 83, passing oversaidpulleys 77, 78, and 80, 81, respectively. The speed of rotation of thecountershaft 35 is thereby largely reduced from that of thedriving-shaft, as is required for rotating the feed-roller at thenecessary slow speed for. proper feeding of the hatbrim.

For adjusting the position of the countershaft longitudinally of themachine, so that the position of the same may be at all times exactlyover the center of the bevel-gear 33, so as to secure the proper meshingof said gear and the pinion 34, the recesses 90 in the feet of thestandards 36, 37, respectively, are made wider than the diameter of thesecuring bolts 91 which secure the standards to the bed 10. Thereby alongitudinal adjustment of the position of the standards on the bed, tothe extent of the difference between the width of the slots and thediameter ofthe bolts, is provided, whereby the countershaft 35 may beaccurately positioned in accordance with changes of position of thefeed-roller which may be made. A corresponding adjustment of theposition of the wet-belt 19 is secured by providing horizontal slots 93in the bracket for the screws 94 by which the same is secured to thestandard 37. By this means the position of the dampening-belt may bevaried and the same brought into proper position relatively to thebrim-guide when the latter is adjusted or readjusted, so as to properlycoact for dampening the brims fed in the new position.

The driving-shaft 64 is supported in a bracket 98 at the rear-portion ofthe bed, or maybe supported in any other suitable manner. Tight andloose pulleys 95, 96, and an overhead driving-belt 97 provide fortransmitting motion thereto and stopping and starting the machinewhenever desired.

For preventing slip of the wet-belt on the driving roller 22 and lowerroller 15, these rollers may be roughened or provided with projectingpins 58, as shown in Fig. 2, so that the belt is positively driven.

The machine described provides a rapid and effective means .for curlinghat-brims in an entirely automatic manner, the only manual operationrequired being the proper feeding of the hats to and through themachine.

It is obvious that the invention is not limited to the details ofconstruction shown and described, and that the same may be changedwithout departing from the spirit of the invention as set forth in theclaims.
